To all whom it may concern: I

Be it known that we, Amman S. Bunuion, a

and Cam. Nmnsuit, a subject of the King of Denmark, who has declared his intention to become a cltizen of the United States, both residing at Chicago, in the county of Cook and $tate of llllinois, have invented certainnew and useful Improvements in Vegetable Milk, of which the followin is a specification.

Our invention re ates to improvements in articular reference to a roduct designed to e prepared mainly or w olly from vegetable materials, the resultant product being suitable for use in cases where the milk obtained from animals, such as cows, is now employed.

The principal objects of the invention are to provlde a substitute for cows milk which may be prepared rincipally or wholly from vegetable materia s; to rovide an article of the class described which may be derived principally from relatively cheap grains or analogous material; to rovide an article of the class described whic may be produced, either in solid or liquid form; to provide a article of the class described which shall have keeping qualities l or suerior to animal milk, le ct being stored for a form without loss of m O l value-or sacriu of the roperties of associate with fresh cows'milk; to rovlde a product at the class descrih whic may be prepared simply and Illllfilyru from relatively cheap mateof on average rials, such as soy be; and, in

general, to provide proved product or article of e chara relerredto. I a l at our product, we prefer to ute as a t a; one ot the leguminous grains,

such as the soy bn.

Subsequently, the clean washed rm are seed in cold water for skins become sulfieitly ml The beans are then suit ably pated, for nee, with a suitable more, from the water used for soaking, which dpeeldtlon at hettera Eatent.

may be discarded. The beans from which the water has been drained 0d are now in condition to be utilized for the preparation of the milk.

During the further treatment of the beans, the skins may be removed from the beans or not, although we prefer to take the entire bean unstripped from the skin so as to ob-.

practically all the protein and fat of the soy ea'ns has been extracted. The milk-like sus- The extraction is carried on until pension is then separated from the rain by passing through heavy muslin, an finally the grains are caused to re up the reming adherent suspension a ressum between filter cloths of heavy mus in in a suitable press.

'lhe watery extract or suspension which constitutes the base lor'the vegetable milk of our invention has an appearance similar to that of cows milk "and contains vegetable fat and vegetabl protein in a er suspension than occurring in ordinary cows milk. e percentage of cane sugar in the met is extremely small and, if desired, an additional quantit of sugar, tor instance, either milk sugar, g ucose, maltose, or cane sur, as requlred, may be added in the proportions necessary to secure a vegetable milk containing the several constituents needed for body nutrition. Also, analysis of the milk, certain quantities ot the important deficient salts, such as those of sium, potassium, calcium, and magnesium, either chlorates or phosphates, or both, may be added to correct any actual or fancied deficiency in such elemen ln order to facilitate the d render it convenient tor it found desirable upon 7 llllll shippin purposes, we prefer to evaporate the pro uct to dryness in a suitable vacuum apparatus.

Sterilization of our improved soy bean milk may be efiected without sacrifice of any of its desirable properties and without separation of any of its ingredients. It may also be stated that our improved vegetable milk prepared as above and to which the necessary amounts of sugar and these saltshave been added, is superior in certain respects to cows milk as a food, because of its higher protein content and because the necessary food elements, including the vitamins, are present in balanced proportions. It may be used to advantage instead of cows Our invention is not limited to the par I ticular details set forth in the above description, which are merely illustrative of one milk. The scope of the invention should be determined by reference to the appended claims.

We claim- 1. The process of preparing vegetable milk from a grain, which consists in soaking the grain in water, draining oil the water, mashing the grain, extracting the mash with water, and subsequently separating the extract from the inextractable residue.

2. The process of preparin vegetabl milk from soy beans, which consists in soaking the beans in water until softened, mashing the softened beans, extracting the mash with water, removing the extract from the inextractable solids, adding deficient elements such as sugar and tissue salts, to the milk-like extract, and subsequently evaporating the-product to dryness.
